T0 all whom it may concern.-

Beit known that l, FREDERICK Romain, of New York city, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Carbonating Apparatus; and l do hereby declare thefollowing to be a full, clear, and exact dcscription of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and to the reference-numerals marked thereon.

My present invention relates to improvements 1n the art of carbonatingliquids; and it is the purpose of my invention to provide an apparatusof-this character whichis capable of producing the carbonated or aeratedli uid 'directly from the gas and water or other liquid which may beemployed through the medium of a commin'gling chamber which is of such aconstruction that a thorough impregnation is secured without thenecessity of employing mechanically-agitated devices such as are oftenfound necessary in other apparatuses.

To these and other ends the invention consists in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the speci- '.tication.

in the drawings, Figure l is a diagrammatic view showing the method ofconnecting up an apparatus embodying my invention; and F ig. 2 is asectional view thrmigh the commingling-chamber, showing the interiorconstruction and arrangement of its parts.

ASimilar reference-numerals in both ligures indicate similar parts.

Heretofore in the process ol" carbonating liquids it has been customaryto lead the water and gas se arately to a mixing-chainber which usua ycontains some suitable agitator through the operation of which the wateris impregnated with the gas, some systems employing a supplementaldevice, such as a series of plates over which the partially-- mixedliquid 1s assed in thin iilms to en able it to absorb sufiicicnt gas;but those devices are not only very expensive and complicated, but theydo not thoroughly impregnato the liquid with the gas; and it is thepurpose of my present invention to simplify the construction andoperation of the apparatus and te secure a more perfect oarbonlzation ofthe liquid.

The present embodiment oi my invention comprises generally thererigerating-chainber 1, within which is preferably iocated the coil 2,through which 'water from the supplypipe 3 passes in order that itstemperature may be reduced before it reaches the gas, this supply-pipe3- connecting, preferably", with an ordinary service-pipe which isusually supplied under pressure. This coil 2 eonneets at its oppositeend with the comininglingchamber 6 at the connection 7, and adjacent tothis connection 7 is provided a similar connection 8, with which isconnected the gas-supply pipe 9, which leads to the connection l0 of apressure-re fulator 1l. This .chamber 6 embodies genera iy a hollowcylindrical casing l2, to one end of which are connected the littings 7and 8 and at the unposite end is connected the fitting i3, whichconnects by the pipe 14 with a settling receptacle or reservoir l5, tothe op osite end of which is connected pipe 1G, W lich leads to thedraft-arm 1,7 of the soda-fountain or other dispensing apparatus.

.lvtfithin the casing l2 is mounted a tube le, which is preferablyarranged concentrically within the casing and connects at 'one end 'withthe iitting 8, which connects with the gas-simply pipe 9, suchconstruction 'forming annular chamber which surrounds this tube andforms a communication between the water-supply pipe 2 and the pipe i4.'ll he tube l is provided at suitable intervals with orilices it), andover the tube adjacent to each oril'icc is litted a sleeve T20, eachhaving a portion adapted to snugly fit the tube to retain it inoperative position and provided with a hollow annular extension 2l,which is comparativelythin, and it lorms an annular space 22 between itand the tube '1.8, the sleeve 20 being so adjusted on the tube that theannular chamber 22 will connnunicate with the corresponding oriiice 19of the tube, those portions of the sleeve 20 in which are formed theannular chambers 22 being so arranged that vthe openings in thesechambers are directed away from the fittings 7 and S and toward theiitting 13 at the opposite end ol' the chamber for a purpose that willpresently appear.

Any suitable source of gas-supply may be employed but l prefer to usethe ordinary receptacles or tanks 23, which are charged with vhigherinitial pressure than that of the liquid to be carbonated, and to thesetanks are connected the pipes 24, which are provided with ICO semer 33 Iclaim as Inynvention 1. The combination with sources of liquid and gassupply under pressure, and regulating means for maintaining apredetermined ratio between the pressures of the liquid and gas, of acarbcnator for mixing'the liquid and gas embodying a hollow casinghaving communication at one end with the source of liq udlsupply andprovided with a discharge at its opposite end, said casing forming apassage for the liquid during carbonization, and a nozzle inclosed byand spaced from the-walls of said casing and communicating with thesource of gas-supply', said nozzle having a contracted gas-dischargeorifice, and a sleeve on the nozzle having an enlarged interior eXMpansion-chamber for receiving gas from the discharge-orifice andpermitting it to expand, the said chamber of the sleeve 'having anenlargeddischarge-oriice fr -spreading the gas and introducing itin theform of a film of enlarged surface and reduced pressure to the liquidcontained in the casing.

` I2. A carbonator embodying a hollow cascommunicating at one end with asource of i quid-supply and having a discharge at its opposite end',forming a passage for the liquid to be carbonated, a tube inclosedtherein and spacedfrom the Walls of the casing to form a mining-chamber,said tube being in communication with a source of gas-supply underpressure and having a discharge-orifice therein, and a gasegrpansion andtemperature" equalizing chamber embodying a sleeve arranged between thenozzle and the outer casing having a hollow extension with thin Wallsspaced from the nozzle and projecting over the discharge-orifice to forman enlarged eX- pansion-cliamber, the thin walls of which are in contactwith the liquid, whereby gas under pressure issuing from the oriiiceinto the ex pansion-charnber Will expand into an annular film ofenlarged surface the temperature of which will be equalized with that ofthe liquid before mixture through the thin Walls of theexpansion-chamber;

3. in a carbonator, the combination with a hollow casin(r communicatingat one end with a source of liquid-supply and having a discharge at itsopposite end, of tube inclosed within the casing and spaced from theWalls thereof to forni a mixing-chamber, said tube being connected to asource of gas-supply under pressure, and having a series ofdischargeorifices spaced lengthwise thereof, and a series of"ass-expansion and temperature-equalizing c` ambers spaced lengthwise ofthe gastube for the discharge-orifices, each ernbodying a sleeve havingthin Walls spaced from the tube forming an enlarged.expansion-chamberfor receiving the gas under high pressure from the oriiice, expanding itinto a film of low pressure and enlarged surface and intro` ducing it tothe liquid in such form, the outer surface of the thin walls of thesleeves being in contact wi th the liquid and acting to equalize thetemperatures of the latter and the gas before mixing.
